I was able to drive a Toyota Yaris all the way to the Blank Gulch TH. Easily passable with any car that is able to drive on semi-rough roads. The road is rocky, and has some wash boarding in a few places. You will have to drive over some cattle barriers along the way. The trail up is very rocky and rugged, and signed very well. I think I was on the East Slopes Trail. Not sure... There where a lot of blown down tree's on the trail, but they have all been cleared off.
